Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

The check engine light comes on without any incident or identifiable reason. I've changed the gas cap, cleaned the sensors, replaced other sensors and controllers, but always with the same code that indicates that a sensor was faulty. Very frustrating, especially when the check engine light goes out while driving and no maintenance or event could be cause for the light to go out. This is a pain, since every time it happens, I service the vehicle to eliminate these "ghost" signals.
